23 is a sliding spindle which is held in the bonnet 22 and bushing 21,and 24 is a packing nut the outer face of which is screw threaded andengages with a screw thread on the inner face of the bushing 21, asshown and a packing 26 and 27 respectively, is engaged with by said nuts24 and 25 to tightly close the space around this sliding spindle 23.

28 is a plug, the outer face of which is screw threaded and engages witha screw thread on the inner face of the chamber 20 to tightly close thischamber 20 by this plug 28.

The operating spindle 17 is provided with a crank 29 and the latter isprovided with an enlarged slot 30. The sliding spindle 23 is providedwith an arm 31 which extends over the spindle 23, as shown, and 32 is abolt with an enlarged head 33 which is provided with a nut 34, part ofthe shank 35 of which is formed larger and works, in the enlarged slot30 and is formed with a shoulder 36 which abuts against the arm 31 ofthe spindle 23.

37 is the chamber which is divided into two compartments, 0, (Z, by thestationary valve plate 38 and in this stationary valve plate 38 theports or passages 39 are formed.

40 is an arm provided with an operative valve plate 41 in which theports or passages 42 are formed.

43 is an annular flange formed in the regulator 8 in which thestationary valve plate 38 is secured.

The arm 40 extends beyond the sliding spindle 23 and said arm isprovided with a slot hole 44 which is formed larger in one cross sectionthan the other, and the sliding spindle 23 is provided with nuts 45 and46 which screw onto the screw threaded end of said sliding spindle 23.

47 is a bonnet, provided with a screw thread on part of the outer facewhich engages with a screw thread on the adjacent face of the regulator8, as shown, and the screwing of one into the other tightly closes theopening at the point where the bonnet 47 is secured to the regulator 8.

48 is a pressure plug which is threaded into the bonnet 47, and 49 is acap nut which is threaded on the pressure plug 48 against the bonnet 47,as shown.

50 is a spring pressure spindle which is formed with an enlarged head51, and said pressure spindle 50 rests in the bonnet 47 and the pressureplug 48, as shown.

52 is a packing which is inserted and held in place against the pressureplug 48, and between the end of the bonnet 47 and the cap nut 49.

53 is a shoulder formed on the pressure spindle 50, and 54 is a washerwhich encircles said spindle 50 and abuts against the shoulder 53 at oneside.

The spring abuts at one end against the washer 54, and the other end ofthis spring abuts against the inner shoulder 56 of the pressure plug 48,and at the same time this spring 55 encircles the pressure spindle 50.The pressure spring 55, in its normal condition, holds the pressurespindle 50 against the arm 40 of the operating valve plate 41. The arm40 is slotted as at 44 and through which extends a spindle 23. The slot44 extends longitudinally of the arm 40 and the length of the slot isgreater than the diameter of the spindle, while the width of the slot isslightly greater than the diameter of the spindle. By this arrangementthe arm 40 can be shifted through the action of the spring 55 and head51 so as to hold the plate 41 against the plate 38 and furthermore toallow plates 38 and 41 to expand and contract which would not be thecase if the arm 40 was fixedly secured to the spindle 23.

whether or not a water or steam inlet is used.

In the partition, 6, the valve seats 61, 62 and 63 are used for thepurposes which will be hereinafter set forth. The regulator 8 has threebonnets 64 which are screw threaded therein, and 65 are the valvespindles each of which are screw threaded into the bonnets 64, as shown.Each of these bonnets 64 have a packing nut 66 which is screw threadedthereon, as shown, and in each of these packing nuts 66 a packing 67 issecured, these nuts 66 therefore hold the packing 67 against the spindle65, the nuts 66 and the bonnets 64.

68 are the enlargements on the spindles (S5, and 69 are the swivel capsone of which is secured on each of the enlargements 68, as shown; and 70are the valves which are screw threaded on the swivel caps (39, asshown; and said valves 70 are adapted to fit into the valve seats 61, 62and 63 for the purpose which will be hereinafter setforth.

71 is a bolt which secures the clamp 72 to the sleeve 14, and 73 is thearm of said clamp 72 in which the hole 74 is bored.

75 is the segmental plate which may be keyed or otherwise secured to thespindle 17,

and in this segmental plate 75 the teeth 7 6 are formed.

The hole 74 is formed to receive the worm wheel 77, and 78 is the shaftof this worm wheel 77 which shaft 78 is held in the sides of said arm73, and said shaft 78 is provided with a hand wheel 79; this Worm wheel77 is therefore adapted to fit in the teeth 76 of the segmental plate75.

81 is the indicator secured to the projection 82 of the clamp 7 2 by thescrews 83, and the float arm 84 carrying the float 85 is secured to thesleeve 14 by the screw 86 and the bracket 87.

88 is a set screw which extends through the body of the regulator 8 andis adapted to abut against the stationary regulating plate 38 to hold itin the chamber 37 of the regulator 8. s

89 is a packing nut which is screw threaded onto the thread of thesleeve 14, as shown, and holds the packing 90 against the spindle 17 andthe end of the sleeve 14.

The boiler, not shown, is connected by the steam connection 3 and thewater connection 4 with the water column 1, and sometimes by the waterconnection 5, but the water connection 5 is more often used as a blowoff. The gage glass 6 shows the height of the Water in the water column,1, and boiler; and the indicator 81 shows the operation of the float 85,and the indicator gage 7 indicates in the water column the height of thewater. The regulator 8 automatically controls the supply of water to theboiler it being connected to the water column 1 and without anypossibility of the operative valve plate 41 sticking. The toothedsegmental plate 7 5 is secured to the operating spindle 17, and the wormwheel 77 is supported in the arms 7 3 and the latter is secured to thesleeve 14. By operating this worm wheel 77 the segmental plate 7 5 aswell as the spindle 17 is operated to give a greater or less flowthrough the valve plates 38 and 41, by raising and lowering the slidingspindle 23. If the worm wheel 77 is operated, the toothed segment 7 5 isalso operated, this operates the spindle 17 and crank 29 thereon, asshown, in Fig. 6, which is connected to the sliding spindle 23 by a bolt32 which raises and lowers the sliding spindle 23 so that the ports orpassages 42 in the operative valve plate 41 are operated more or lessover the openings 39 in the stationary valve plate 38.

It will be noticed that in the application of this improved automaticfeed water regulator, it works automatically, it works in a simple,durable and economical manner, it is simple in installation, it isapplied to a water column or present connections without mutilation ofthe boiler, it keeps the water at one level, and gives dry steam, thuseffecting a saving in fuel by so doing.

These devices or similar devices may be connected to one another and toa battery of boilers, of the same or different steam pressures, and allfed by the same pump, yet controlling the water level in each, and byopening one valve any boiler may be flooded when desired.

Having thus described my invention, I claim 1. In a device of the classdescribed, an

operating spindle, means operated by the spindle to control the flow ofwater to the boiler, a sleeve surrounding part of said spindle, meansfor operating the sleeve, a clamp secured to said sleeve, an indicatorsecured to said clamp, an arm secured to said clamp, a worm wheelsecured to said arm, in combination with a toothed segment secured tosaid spindle, and the teeth of said toothed segment engaging with saidworm wheel, and operating means for the latter whereby said segment isshifted.

2. A device of the class describedcomprising a casing provided with aplurality of compartments one arranged above the other, said uppercompartment formed with a partition provided with a valve seat, thelower wall of the upper compartment constituting the upper wall of thelower compartment, said lower wall provided with a pair of valve seatsadjustable valves adapted to engage the valve seat in the partition andthe valve seats in the lower walls whereby communication is closedbetween both sides of the upper chamber and between the lower and theupper chamber, a stationary and a movable valve plate mounted in thelower chamber and constituting a divisional means to divide said lowerchamber into two compartments, and means for adjusting said movableplate with respect to said stationary plate for regulating the flow ofwater from one of the compartments in the lower chamber to the othercompartment of said chamber.

In testimony whereof, I have signed in the presence of the twoundersigned witnesses.
